If a helicopter requests practice Controlled Controlled Approaches (CCAs), with whom must CATCC coordinate?

When a helicopter requests practice Controlled Controlled Approaches (CCAs), coordination is primarily essential with the Air Officer. The Air Officer is responsible for overseeing all air operations and ensuring that the airspace is managed effectively during such training exercises. They play a critical role in maintaining situational awareness and ensuring that all aircraft are safely integrated into the operational environment.

In this scenario, the Air Officer would coordinate directly with the necessary entities to facilitate the practice approaches, such as ensuring that air traffic control is aware of the helicopters' movements and that any other aircraft in the vicinity are informed of the training activity. This coordination helps to maintain safety and efficient airspace usage during the practice sessions. The Air Officer’s oversight ensures that required procedures are adhered to and that all involved are properly informed.

The other options, while they may have important roles within the overall air operation system, are not primarily responsible for the coordination required in this specific context of practice CCAs.
